Abstract:
    Input signals are weighted by weighting means composed of variable resistors 11-1 through 11-n, each made of an oxide thin film with a perovskite structure containing manganese, which changes resistance at room temperature according to the cumulative number of times a pulse voltage was applied and holds the resistance in a nonvolatile manner. Then, the weighted signals are inputted to an arithmetic unit 12. The oxide thin film used as each of the variable resistors 11-1 through 11-n changes its resistance, according to the cumulative number of times the input pulse was applied, and further holds the resistance in a nonvolatile manner even after the power supply is cut off. Thus, by changing the weighting factor according to the cumulative number of times the pulse voltage was applied, a neuro element more resembling a neuron of the human being is realized.
